GeForce 810M vs Radeon HD 5770

Intro

Compare all that to the Radeon HD 5770, which features a core clock frequency of 850 MHz and a GDDR5 memory frequency of 1200 MHz. It also features a 128-bit bus, and makes use of a 40 nm design. It features 800(160x5) SPUs, 40 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
Radeon HD 5770		108 Watts
	Difference: 93 Watts (620%)

Memory Bandwidth

The Radeon HD 5770, in theory, should perform quite a bit faster than the GeForce 810M overall. (explain)

Radeon HD 5770		76800 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 62400 (433%)

Texel Rate

The Radeon HD 5770 will be much (more or less 476%) faster with regards to texture filtering than the GeForce 810M. (explain)

Radeon HD 5770		34000 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 28096 (476%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon HD 5770 is the winner, and very much so. (explain)

Radeon HD 5770		13600 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 10648 (361%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
